Expert Ayurveda — not refunding my money

Address: New Delhi, Delhi

I had purchased 3 months weight loss medicine from expert ayurveda company. I took medicine for a month but there was no effect, so i called them, they asked me to send back the medicine and they will refund me my amount. But after sending the medicine they did not refund my amount. I request all the customers suffering from the same problems should come together and file a police complaint. I have all the details about all of them so please join together and punish these cheaters.
